The May Massive

How big will your May be...?

Challenge Ended: May 31, 2013

To kick off the recently announced Monthly Training Series, we're challenging you to run as many kilometers as you can during the month of May.

No specific distance goal for this Challenge, it's just an open call to get out there and push yourself. To keep you motivated along the way, there are four milestone achievement badges to be earned. They start at 40 km and go all the way up to 160 km.

Whether you start the Challenge on May 1st or join in the last week, make the most of your efforts and do something truly massive this month!
